Point me to parts & rebuild kits etc.? '66 Signet /6

Wow! A lot to cover there! OK so here's what the '66 has now:

-Rebuilt carb (total reman., by a great shop here in Richmond, CA)
-MSD 6AL, along with complete replacement of all ignition parts just the other day (with the 6AL, it's smoooooth)
-Gutted, fully gone-through rear diff. and brakes (those 7.25's do last if you don't race)
-Rblt master, replaced front brake shoes (crappy pads it seems, but ok for now)
At 130k it runs really nice and has a lot of life, but yeah I can feel at least the trans mount is shot and it needs shocks before anything else.

My long-term goal is a firm front suspension, front discs (small bolt to keep my rallys), and some basic rework on the engine's top end (intake, carb, head, exhaust). All bolt-on stuff basically. I know the poly front end is firmer and that's worth the extra few bucks now, I'll do it with the shocks & alignment (and 2 fresh tires up front!).

So, I suppose since the brakes are good enough, I will use 'em till I lose 'em (several SBP disc kits I have found, that's outta my price range till summer). I appreciate the tune-up articles as well, perhaps I can squeeze a couple more MPG outta this thing!

So it seems like all my questions have been answered! Oh, and I know the MSD boxes are very HEI friendly so that's a good thing too!
